调用Microsoft Dynamics CRM 2011 sdk IOrOrganizationServiceProxy web服务时发生SOAP安全协商错误

我们公司有一个虚拟机，其中安装了sqlserver和crm 2011，我们使用它来测试代码，我还编写了一个简单的Web服务，称为sdk IOOrganizationServityProxy Web服务。在这个虚拟机上，我的代码运行良好，没有错误。但情况是这样的：我们还有另外两个虚拟机，其中一个安装了sql server，另一个安装并配置了crm。crm工作正常，但当我尝试使用调用crm sdk IOrOrganizationServiceProxy webservice webmethods的web服务时，我发现以下错误，有什么想法可能是错误的吗？提前感谢所有回答这个问题的人

下面是我的visualstudio调试模式中的一个图像，显示了错误：

它可能不适用，但当我使用的URL与CRM部署管理器中设置的WCF绑定不匹配时，我遇到了问题

例如，名为“MyCRMServer”的服务器可能正在侦听端口80上的以下位置：

http://MyCrmServer/

…但如果我已将部署管理器中的CRM服务器更改为url“CRM.myCompany.com”，则我必须使用此url访问web服务：

http://crm.myCompany.com/
